They broke up in the "Hawkeye & Mockingbird" series, though they did keep working together in "Widowmaker". Basically what it all came down to was, although they gave it another go, they had just changed too much since they last saw each other, especially Bobbi. The book also made it seem like Bobbi was on a bit of a slippery slope, being pushed to the limit and acting out of desperation, and she was bringing out similar qualities in him - so they hit pause, and though they've had moments of closeness since, that's sort of where things seem to be right now.

Meanwhile, as you noted, Clint's been flirting with Spider-Woman in the pages of Avengers, and we'll have to see where things shake out with everyone going forward.

Also, yeah, she was briefly in a coma. What happened was that she got shot (in New Avengers) and was in critical condition. Nick Fury got them a version of the Infinity Formula (the serum he took that radically slowed his aging) that had been mixed with some Super-Soldier Serum (the stuff that turned Steve Rogers into Captain America), so she woke up with some superpowers. They seem similar to Steve's powers, but we'll have to see what all she's capable of as the story unfolds - the other dangling question is whether this will halt her aging, too - lots of unanswered questions so far about the effects.
